I am not going to say it does not happen, but I instruct and get the "noone told me" all the time. "Well what about where you initialed you had received this training ?" "Oh, well , maybe someone did tell me and I just forgot or maybe I need to stay in the books more." In all due fairness, NJA is like a fire hose for the first six to twelve months, depending on your learning curve - and please SPARE ME any more retired airline pilots - as a group, not individually !!
